MACHINE FOR TRININIING WALL-PAPER.

SPECIFICATION forming part of Letters Patent No. 647,053, dated April10, 1900.

Application filed August 2, 1899. Serial No. 725,857. (No model.)

To all whom t may concern:

Beit known that I, HENRY M. UNDERWOOD, a citizen of the United States,residing atWaukegan, in the county of Lake and State of Illinois, haveinvented certain new and useful Improvements in Machines for TrimmingWall-Paper, which arefully set forth in the followingspeciicatiomreference being had to the accompanying drawings, forming apart hereof; and in whichf Figure l shows my said new wall-paper trimmerin front elevation. Fig. 2 shows a detached view of the under side ofthe adjustable paper guard and guide or paper-protector. Fig. 3 shows atransverse section of Fig. 1 on the cutting plane Qc 0c. Fig. 4 showsthe gear-wheels in end view, the conical winding-spindle being partlyremoved from the machine and a part of the gearing broken away. Fig. 5shows in perspective the adjustable paper-guides f, guard j, andadjustable guide-holders.

Like letters of reference denote like parts. The object of my inventionis to improve the construction and operation of my earlier patentedpaper-trimmers; and to attain said ldesirable end I construct my saidnew inachine in substantially the following manner, namely: Y i

' I make two metallic standards d, which are secured together by threestrips, of wood b, b, and b', thus forming a frame for carrying theparallel uniform-diametered shafts c, a speed governing roller or drum dona shaft d', and

a winding rod., spindle, or drum c to receivethe trimmed paper. Upon thestrip or supporting-barb' are mounted longitudinally-adjustablepaper-guidesf, below which on a rod f2 the roll of paper to be trimmedis mounted and passes to the circular and longitudinallyadjustablecutters h and h. Said guides are provided at their upper ends with largesquare openings or eyes f', through which freely passes thesupporting-strip Z9', and in each of said eyes is also held the outerend of a guideholder t', held by screws t" through said eyes parallel toand under the supporting-strip b. Slots f3 admit the rod f2, loaded witha roll of paper it. On the under side of one of the woodenguide-holderst'is also secured an alinement-guide 2, preferably ofmetal,which passes through loops or staples t3, secured in the opposite-guideholder i, and in each of said guide-holders z' is also secured ascrew or stud 4, eachof which holds an end of a tensioned spring i5. Tothe upper and outer edges of the gnidesfare lugs g, integral with saidguides and surrounding the eyes f', and through the one nearest thecrank r passes a set-screw g to iixedly hold its guide f to the bar orstrip b', and a pin or rivet g2 also pass ing through the said lug andthrough a sheet metal guard or paper-protector j, thus secura ing saidguide-holder and guard together. The opposite or free end of saidprotector j passes freely through the eye f of the opposite guide f, andits front part projects down over the front edge of the supporting-barb'. The metallic guardj supports the paper undisturbed in itslongitudinal motion, while at the same time an adjustment may be madelongitudinally to the moving paper, so as to bring it to the intendedline at the cutters, this being done without crinkling, folding, orotherinjury, which is the case when the guides gears r, present therebyconstantly-changing wearing-surfaces, which'are thus kept in the bestworking condition, and about directly over the supporting-bar b is awinding-spun dle e, held in open or forked bearings Z, one journal ofsaid spindle being provided witha belt-pulley m2 on the pulley m on thedrivingshaft. Said drum d is covered with a rough cloth cl2 to increasethe friction of the paper n, (shown in the broken line,) passing fromthe rod f2, where it is a roll put on the machine, thence unrolled andpassed between the cutters h h', thence under the drum d, and up andaround the winding-spindle e. Said governingshaft d is of about the samediameter as the cutters at their pitch-circle or points of intersectionof the cutting edges,

'f alone are relied on, and the paper-support n IOO and its arrangementin the gearing 7.: is such that it will run slightly slower than saidcutterspracticallyaboutone-ninthslowerand its mounting is such that itslower face or edge, the point of con-tact of the shears, and the'top ofthe metallic guard j are all in or nearly in the same plane. Saiddifferential gearing of the shears and slower gearing of the roller dcauses the cutters to part the pa` per Without producing fuzz, whichinterferes with the appearance of the trimmed paper. The' taperingspindle e winds the trimmed paper, and as the roll increases the crossedbeltmslips more and more, as itis arranged to do, to prevent tearing orfaster running of the paper than it is delivered by the feed-gov,-erning drum d. The average speed of the spindle e is to be about thesame as that of the drum CZ. Pulleys p, just outside of the cutters hh', carry cord belts q q over the drum d, against which the waste orseparated strip of paper w curls, and which carry said waste outwardlyand cause it to fall outside of the machine, thereby preventingentanglement of said material with the working mechanism. The belt mholds one end ot' the winding-spindle c into its bearings, and a hook o,secured to the shaft ot' the drum d and hinged thereon, holds the otherjournal of said spindle in its bearings. Handles f X are attached to theouter and lower edges of the guidesf, which are grasped when moving saidguidesflongitudinally on theirsupporting-bar b'.

To use the machine, lirst' set the rotary cutter h with its belt q toits longitudinal position on the axle, then set the right-hand guidefand hold it by the set-screw g', set

the cutter h if it is to be used, and if not' then set it out of the wayto the left, put a roll of paper on the rod f2, and bring the oppositeguidefagainst the end of the roll by means of a properly-tensionedcontracting spring t5, and then pass the end ofthe paper through themachine, through the cutter h', and around the back of the drum CZ andallow it to wind on the spindle e, while turning the crank r. If twocuts are to be made at the same time, set the cutter 7L and its belt qto their proper places and otherwise manage, as before, for a singlecut. If the paper needs adjustment to cut on the proper lines, loosenthe set-screw g and take hold of the handle fx, which will enable you topull at it in the right direction and move paper-protector guides andpaper-roll longitudinally .to its proper place while the machine is atwork. By means of my said construction I am enabled to split a roll ofpaper into as many strips, plus one, as there are cutters providedtherefor, and all the strips so cut may be rolled around thewinding-spindle at the same time. I am also enabled to split rolls ofpaper with border designs into their respective borders.

What I claim isl. The combination with spring-connected roll-holdingpaper-guides, of a longitudinally-adj ustable sheet-metal guard securedto one of said guides and slipping freely through a hole in the oppositeguide, substantially as specified. v

2. The combination with spring-connected paper-roll-carrying guides, ofa longitudinally-adjustable sheet-metal guard secured to one of saidguides, a supporting-bar and a set-screw in the guide holding saidguard, substantially as specified.

3. The combination with a supporting-bar and a longitudically-adjustablesheet-metal guard thereon, of paper-guides longitudinally adjustable onsaid supporting-bar, and means to adjust and hold to place one of saidguides, substantiallyas specified.

4. The combination with a supporting-bar and longitudinally-adjustablepaper-guides, one tixedly adjustable and the other automaticallyadjustable, of spring-actuated longitudinal guide-holders txedlyattached to said paper-guides and a guiding-rod connected to saidguide-holders, substantial] y as specified.

5. The combination with differentiallygeared rotary cutters, ofpaper-guides, one xedly adjustable and the other automaticallyadjustable to Said fixed guide, a longitudinally-ad j ustablesheet-metal guard secured to said tiXedly-adjustable guide',longitudinal guide-bars fixed to said paper-guides, and a guiding-bar tosaid longitudinal guide-bars, substantially as specified.

6. The combination with rotary cutters, of a feed-governing drum andendless belts and pulleys near the outer sides of said cutters on'thecutter-shaft, saidbelts on said pulleys and said feedgoverning drum todeposit the trimmings, substantially as specified.
